GnRH agonist versus HCG triggering in different IVF/ICSI cycles of same patients: a retrospective study.

GnRH agonist versus HCG triggering in different IVF/ICSI cycles of same patients: a retrospective study. J Obstet Gynaecol. 2019 Dec 03;:1-6 Authors: Yılmaz N, Ceran MU, Ugurlu EN, Gülerman HC, Engin Ustun Y Abstract The aim of this study was to assess Gonadotropin Releasing Hormone agonist (GnRHa) trigger results of fresh in vitro fertilisation (IVF), Intracytoplasmic Sperm Injection (ICSI) cycles in high-responder patients. Thirty-six high-responder patients, undergoing GnRH antagonist protocol combined with GnRHa trigger for final oocyte maturation, were included. All cycles were autologous fresh transfer cycles. Fifteen of 36 patients had previous IVF/ICSI cycles triggered with human chorionic gonadotropin (hCG) and both cycles of these patients were compared. The mean fertilisation rate, blastocyst development and clinical pregnancy rates were 67%, 44.4% and 44.4%, respectively. The hCG and GnRHa trigger cycles of the same patients were compared as two groups (n: 15). 2PN oocyte counts were significantly higher in agonist trigger cycles (p .048). There were no differences in terms of M2 oocyte count and fertilisation rate. The blastocyst formation and clinical pregnancy rates for hCG and GnRHa trigger cycles were 33.3-66.7% and 13.3-46.7%, respectively. These results were found to be 2-fold and 3.5-fold higher, but not statistically significant. GnRHa trigger in combination with LPS is a good option for final oocyte maturation due to its good p...

Authors: Yang DN, Wu JH, Geng L, Cao LJ, Zhang QJ, Luo JQ, Kallen A, Hou ZH, Qian WP, Shi Y, Xia X Abstract This meta-analysis was intended to evaluate the effects of intrauterine perfusion of peripheral blood mononuclear cells (PBMC) on the pregnancy outcomes including clinical pregnancy rates, embryo implantation rates, live birth rates and miscarriage rates of infertile women who were undergoing in vitro fertilisation (IVF) treatment. By searching Pubmed, Embase database, five articles meeting the inclusion criteria were included, and 1173 women were enrolled (intrauterine PBMC group: n = 514; NO-P...

Abstract A significant proportion of couples at reproductive age rely on assisted reproductive technology to overcome infertility. In vitro fertilisation (IVF) involves typically the use of exogenous gonadotropins to stimulate the ovary to produce oocytes, which are collected surgically. After fertilization by conventional IVF or intracytoplasmic sperm injection (ICSI), embryos are cultured in the embryology laboratory for a few days before being replaced into the uterus (fresh embryo transfer). Spare embryos can be vitrified and stored in liquid nitrogen to be transferred in a subsequent cycle. Over the years, co...

CONCLUSIONS: This review raises important questions regarding the merit of long-term GnRH agonist therapy compared to no pretreatment prior to standard IVF/ICSI in women with endometriosis. Contrary to previous findings, we are uncertain as to whether long-term GnRH agonist therapy impacts on the live birth rate or indeed the complication rate compared to standard IVF/ICSI. Further, we are uncertain whether this intervention impacts on the clinical pregnancy rate, multiple pregnancy rate, miscarriage rate, mean number of oocytes and mean number of embryos. In light of the paucity and very low quality of existing data, part...

Couples are classified as having unexplained infertility when they have tried to conceive for at least one year and no abnormality in semen analysis, ovulation, or tubal patency has been identified. Treatment options for unexplained infertility include expectant management, ovarian stimulation (OS), intrauterine insemination (IUI), OS-IUI, and in vitro fertilisation (IVF) with or without intracytoplasmic sperm injection (ICSI). Cochrane authors conductednetwork meta-analysis on interventions for unexplained infertility.Cochrane Gynecology and Fertility sat down with Dr Rui Wang, the lead author of the study, who answered t...

CONCLUSIONS: This review evaluated different temperatures for embryo culture during IVF. There is a lack of evidence for the majority of outcomes in this review. Based on very low-quality evidence, we are uncertain if incubating at a lower temperature than 37°C improves pregnancy outcomes. More RCTs are needed for comparing different temperatures of embryo culture which require reporting of clinical outcomes as live birth, miscarriage, clinical pregnancy and adverse events.

In conclusion, our results showed that dual administration of G-CSF was significantly more effective that the SC only method. Impact statement What is already known on this subject? A number of studies reported the possible benefits of granulocyte colony-stimulating factor (G-CSF) administration in recurrent implantation failure (RIF) and recurrent pregnancy loss patients; however, it is unclear which administration route is better. What do the results of this study add? Our results showed that G-CSF is a promising and safe agent for increasing live birth rates in patients with RIF. Additionally, dual administration is con...

CONCLUSIONS: There is insufficient evidence of differences in live birth between expectant management and the other four interventions (OS, IUI, OS-IUI, and IVF/ICSI). Compared to expectant management/IUI, OS may increase the odds of multiple pregnancy, and OS-IUI probably increases the odds of multiple pregnancy. Evidence on differences between IVF/ICSI and expectant management for multiple pregnancy is insufficient, as is evidence of a difference for moderate or severe OHSS between IVF/ICSI and OS-IUI.

In conclusion, our study showed no beneficial effect of addition of E2 to luteal phase support on clinical PR in antagonist IVF cycles. Impact statement What is already known on this subject? Luteal phase deficiency is defined as a disruption in progesterone and oestrogen production after ovulation. It is clear that, luteal phase supplementation to improve the outcomes in in vitro fertilisation (IVF) cycles is mandatory. As an iatrogenic complication of assisted reproductive technique, decreased luteal oestrogen and progesterone levels lead to decreased pregnancy rates (PRs) and implantation rates. What the results of this...

Cochrane Overviews bring together the findings from multiple reviews and one of the largest, first published in September 2013, was updated and republished in May 2018. Cindy Farquhar, from the Department of Obstetrics and Gynaecology at the University of Auckland in New Zealand describes this enormous volume of evidence for assisted reproduction." Infertility is defined as failure to conceive after one year of trying. Up to one in six couples will experience this at some point in their lives and many will seek fertility treatment in the form of assisted reproduction. When they do so, they will hope that they are gett...
